My Husband’s Mistress Is Carrying Quadruplets

The fluorescent lights in the lab hum at a frequency that most people can't hear, but I've worked here long enough that the sound lives in my bones. I adjust the microscope stage, my fingers moving with the kind of precision that comes from five years of analyzing genetic material down to the nucleotide. The junior analyst—Marcus, fresh out of grad school—hovers at my elbow, watching me correct his sample prep with the nervous energy of someone who knows they've made a mistake but doesn't yet understand how costly mistakes can be in this field.

"See this?" I tap the screen where his gel electrophoresis shows smearing. "You didn't let the samples equilibrate to room temperature. The proteins degraded."

He nods, scribbling notes, and I feel the familiar satisfaction of catching an error before it becomes a problem. Control. Precision. These are the pillars of my work, the things that make me one of the most trusted DNA analysts in Seattle.

My supervisor, Dr. Reeves, appears in my peripheral vision, holding a manila folder with a red "Priority/VIP" sticker. "Elise, I need you on this one. Rush paternity test. Client paid for the expedited processing."

I take the folder, flipping it open. The mother's name is listed as Leyla—no last name provided, which isn't unusual for sensitive cases. The alleged father is marked "John Doe," sample already logged and waiting in cold storage. Standard procedure for clients who want anonymity.

"When do they need it?"

"Tomorrow morning. Mother's coming in personally to collect."

I glance at the clock. Four-thirty. If I start now, I can have preliminary results by midnight, full report by morning. "I'll handle it."

The lab empties as evening shifts end. I prefer working alone anyway—no small talk, no distractions, just me and the elegant language of base pairs and alleles. I retrieve the samples from storage: maternal blood, fetal DNA extracted from a prenatal screening, and the alleged father's cheek swab in a sealed vial.

The sequencer whirs to life, and I load the samples with the same methodical care I bring to everything. PCR amplification takes two hours. I spend the time reviewing case notes, drinking black coffee from my thermos, organizing my workspace. The leather portfolio where I keep my personal files sits in my bag, and I think about Harrison, probably still at the office, chasing whatever deal he's obsessed with this week. We have dinner reservations at eight that I know he'll cancel.

At eleven-forty, the sequencer beeps. I pull up the results on my monitor, watching the genetic markers populate across the screen in neat columns. The maternal match is clean—99.99% probability. Now for the paternal comparison.

I run the algorithm, and the markers begin aligning. My eyes catch on a sequence in the D3S1358 locus—a rare allele combination, fourteen and eighteen repeats. I've only seen that pattern once before.

My hand freezes on the mouse.

No. That's not possible.

I pull up our calibration database, the file I created three
